The '''Hyundai Rotem J151''' is the first generation [[electric multiple unit]] rolling stock to be introduced on the [[Jurong Region MRT line|Jurong Region Line]] of Singapore's [[Mass Rapid Transit (Singapore)|Mass Rapid Transit]] (MRT) system, manufactured by Hyundai Rotem under Contract J151. 62 three-car medium-capacity [[Hyundai Rotem]] trainsets (186 cars) will be delivered from 2024 onwards and service will commence when the line opens in 2027.<ref>{{Cite news |url=https://www.lta.gov.sg/content/ltagov/en/newsroom/2020/february/news-releases/Hyundai_Rotem_company_awarded_contract.html |title=Hyundai Rotem Company Awarded Contract for 62 Jurong Region Line Trains |date=2020-02-06 |publisher=Land Transport Authority |access-date=2020-02-06 |archive-date=2020-02-06 |archive-url=https://web.archive.org/web/20200206033106/https://www.lta.gov.sg/content/ltagov/en/newsroom/2020/february/news-releases/Hyundai_Rotem_company_awarded_contract.html |url-status=dead }}</ref>

== Tender ==
The tender for trains under the contract J151 was closed on 13 June 2019 with four bids. The [[Land Transport Authority|LTA]] has shortlisted all of them and the results has been released.<ref>{{Cite web|url=https://www.lta.gov.sg/content/dam/ltagov/tender/doc/16646/J151_Sch_Tech.pdf|archive-url=https://web.archive.org/web/20200206065828/https://www.lta.gov.sg/content/dam/ltagov/tender/doc/16646/J151_Sch_Tech.pdf|url-status=dead|archive-date=2020-02-06|title=Contract J151 Schedule of Tenders|date=2020-02-06|access-date=2020-02-06}}</ref><ref>{{Cite web|url=https://www.lta.gov.sg/content/ltagov/en/newsroom/2020/february/news-releases/Hyundai_Rotem_company_awarded_contract.html|title=LTA {{!}} News Room {{!}} news-releases {{!}} Hyundai Rotem Company Awarded Contract for 62 Jurong Region Line Trains|website=www.lta.gov.sg|language=en|access-date=2020-02-13|archive-date=2020-02-06|archive-url=https://web.archive.org/web/20200206033106/https://www.lta.gov.sg/content/ltagov/en/newsroom/2020/february/news-releases/Hyundai_Rotem_company_awarded_contract.html|url-status=dead}}</ref>

==Design ==
Every Jurong Region Line train will feature a livery that is mainly turquoise in color to reflect the line's color on the MRT map. The design features a sleek modern look, with angular LED headlights, similar to that of the [[Bombardier Movia C951/C951A|C951(A)]] trains and [[Alstom Movia R151|R151]] trains in Singapore and the [[MTR Hyundai Rotem EMU|R-Trains]] in Hong Kong. The front cab designs are somewhat similar to the Phase III EMUs of the [[Delhi Metro]], also manufactured by Hyundai Rotem.

The trains are also smaller in size compared to those on other MRT lines to enable them to navigate tighter curves in areas constrained by existing developments along the line.<ref name="JRL length"/>

==Features==
The J151 train will have the following features that make it better than the other rolling stocks:

* Larger Door Closing Indicator - Provides better visibility on door opening/closing status.

* Wider train doors ({{Convert|1.5|m|ftin}}, compared to {{Convert|1.45|m|ftin}} on other rolling stocks) - Provides better accessibility for passengers during boarding/alighting.

* More space for multi-use - Provides greater convenience for passengers with strollers and foldable bicycles (other rolling stocks only have this kind of accommodation at selected cars, and somemore the provision is only half of what the J151 train will provide).<ref>{{Cite web|url=https://www.lta.gov.sg/content/ltagov/en/newsroom/2020/february/news-releases/Hyundai_Rotem_company_awarded_contract.html|archive-url=https://web.archive.org/web/20200206065428/https://www.lta.gov.sg/content/ltagov/en/newsroom/2020/february/news-releases/Hyundai_Rotem_company_awarded_contract.html|url-status=dead|archive-date=2020-02-06|title=LTA {{!}} News Room {{!}} news-releases {{!}} Hyundai Rotem Company Awarded Contract for 62 Jurong Region Line Trains|date=2020-02-06|access-date=2020-02-06}}</ref>

* Battery-powered emergency propulsion - Enables the train to drive to the nearest station for passenger evacuation in the event of a power outage. This is the first time a MRT rolling stock has this feature. While the earlier rolling stock also has emergency batteries, they are only capable of providing emergency ventilation and lighting for evacuation onto the tracks.<ref>{{Cite web|url=https://www.straitstimes.com/singapore/transport/korean-trains-with-battery-propulsion-for-jurong-region-line|archive-url=https://web.archive.org/web/20200206065413/https://www.straitstimes.com/singapore/transport/korean-trains-with-battery-propulsion-for-jurong-region-line|url-status=dead|archive-date=2020-02-06|title=Jurong Region Line to use Korean trains with emergency battery propulsion, Transport News & Top Stories - The Straits Times|date=2020-02-06|access-date=2020-02-06}}</ref>

At the same time, the J151 trains will have the following features that are already found in other rolling stocks, namely:

* Condition monitoring and diagnostic systems - Monitors the train health and detect faults for better reliability. Some trains will also have an Automatic Track Inspection (ATI) system, consisting of cameras, lasers and sensors, to detect rail defects in real-time.

* LCD Dynamic Route Map Display - Provides key information such as system map, station arrival and train doors opening side.

* Perch seats, grab poles and hand grips - Provides better comfort for standing passengers.

* LCD Ceiling Display - Provides key information such as station arrival and train doors opening side.

* Ergonomic seats - Provides a more comfortable ride for seating passengers.

In addition, the manufacturer will also tap on existing suppliers of components and systems that are currently used on other rolling stock on the network, which allows for greater commonality between the rolling stock that streamlines maintenance.<ref>{{Cite web|url=https://www.channelnewsasia.com/news/singapore/jurong-region-line-62-trains-testing-start-2024-lta-mrt-12400456|archive-url=https://web.archive.org/web/20200206065407/https://www.channelnewsasia.com/news/singapore/jurong-region-line-62-trains-testing-start-2024-lta-mrt-12400456|url-status=dead|archive-date=2020-02-06|title=Jurong Region Line fleet to have 62 trains, testing to start in 2024 - CNA|date=2020-02-06|access-date=2020-02-06}}</ref>

==Train formation==
The coupling configuration of a J151 in revenue service is DM1–T–DM2. D stands for "driver's desk", M for "motor" and T for "trailer".

The train cars are assigned a 5-digit serial number ranging from 3001x to 3062x, where x depends on the carriage type. A complete three-car trainset consists of one trailer (T) and two driving motor (DM) cars coupled together, e.g. set 3001 consists of carriages 30011, 30012, 30013.

* The first digit is always an 3.
* The second digit is always a 0.
* The third and fourth digits identify the set number.
* The fifth digit identifies the car number, where the first car has a 1, the second has a 2 and the third has a 3.
* [[Hyundai Rotem]] built sets 3001 to 3062.
The trains are able to be coupled into a 4-car train set if needed to increase train capacity.<ref name="JRL length"/>
